.ZCIaima 1 My invention relates to new and useful improvements in rollers adapted for use on various types of machinery, such as corn Shredders. ear pickers, and the like, and is in the nature of an improvement upon the roller disclosed and broadly claimed in my earlier filed co-pending application S. N. 535,963, entitled, Corn picker roller.

More particularly, my invention relates to the shaping of the circumferential contour of the resilient discs or laminations, and the positioning of each with respect to its adjacent disc so that the composite assembled roller will have a-much greater bite and hence a'greater emciency.

Another object of my invention is the. provision of a composite corn picker roller made up from a plurality of resilient laminations or discs which contain a plurality of humps and depressions at their peripheries and which are arranged in staggered relationship, each with respect to its adjacent lamination or disc.

Another object of my invention is to provide a corn picker roller of greatly increased efllciency without detracting from the durability of the same and without increasing the cost of production thereof appreciably. e

The above and other objects of my invention will become apparent from the following detailed description andv attached drawing.

Referring to the drawing wherein like charviews:

,y Fig. 1 is a side view, partly in section andv partly in elevation, away; and y Fig. 2 is an oblique perspective view.

Referring with more particularity to the drawing, the numeral I indicates an elongated steel shaft upon which a plurality of circumferentially scalloped resilient discs 2, having central apertures 3 are compressed face to face in comsome parts being broken pact relationship so as to make up a composite roller 4.

As indicated in my companion application, these discs are preferably'made of uniform thickness from rubber-like or resilient material vhay ing a number of cotton, rayon,'nyl'on, or other fibers, imbedded therein. In my experience, the most economical source of these discs is worn automobile pneumatic tire casings.

As also pointed out in my companion application, the individual discs 2, making up the com-v posite roller, are held in such compact relatlonship, each with respect to the other, that there is no rotation of the individual discs with re plates 5. This is accomplished by a radially extending U-shaped groove 8 in washers 5 of only slightly greater width and length than pins I.

It will be observed by reference to Fig. 2 that the peripheral edge of each disc -2- is provided l5 with a plurality of. knobs or humps 9 and inp tervening depressions l0. The discs 2 are ar ranged on the shaft l in a staggered relationship so that the hump of one disc is immediately adjacent the depression of the next disc. The

90 discs 2 may have any desired number, from three to six or eight, or even more,fhumps and depressions depending upon the type of work desired to be accomplished. However, the important thing is that the humps and depressions shall be uniformly spaced around the circumference of the discs so that the humps of one disc are always immediately adjacent the depressions of the next disc.

Furthermore, while I have shown the humps acters indicate like parts throughout the several and depressions f the discs z as being uniformly wavy in contour, the precise shapeof the humps and depressions is not important. The important thing is to create a rough, tough and durable vsurface in an inexpensive manner and this I have found can be accomplished' best in the immediately above described manner.

In accordance with the patent statutes I have disclosed a complete device for thepurposes had in view, but it will be understoodthat the same is capable of various modifications all within the scope of the invention herein disclosed and claimed.

What I claim is: l 1. A roller comprising an elongated shaft and a composite laminated roller body made up of a plurality of rubber discs in compact relationship, said discs being of substantially uniform thickness throughout their depth and being circumferentially scalloped at their peripheries to provide uniformly spaced peripheral humps and depressions which are co-extensive with the width of the discs, said discs being so arranged on the shaft that the humps of one thereof are circumferentially staggered with respect to the humps of the immediately adiacent disc.
